What is externalPortReceivedBadCrcPackets?
This read-only Counter64 tracks the cumulative count of packets received on the external port with an invalid CRC. It points to physical-layer problems, such as a bad cable or SFP, or possibly malformed-packet activity arriving from the internet side. For example, an admin sees externalPortReceivedBadCrcPackets climbing and checks the external fiber connection for degradation.
